I’m a bit disappointed with the endstop arrangement, The adjustment part on the EVA can’t be adjusted once it’s assembled (I’m using a BMG extruder option), so not sure why it’s made adjustable. The switch is held in place by screws that screw into the plastic arm and I overtightened one so I then needed to add a nut on the other end. It would be a better to go with nuts from the start I think. Then the switch lever contacts only the very outer corner of the block which also has the problem others have described as a very thin plastic base. I redesigned my block to eliminate these last two issues as I felt the end stop will become unstable over time if I left as it was.
This step seems out of place in the frame assembly. There doesn’t appear to be any advantage to doing in here, it can be done later and then it won’t be in the way of frame adjustments.
I agree with the need for a tolerance. Is 1mm too much? 0.5mm? I understand that it needs to be square all round but you could be at this a LONG time if you tried to get it to 0.2 mm!
