I am at the step right before pouring concrete on my MR-1 but would like to check in on a concern I have or get a recommendation.
On my y-axis rails, I have met all the dimensions, except for the diagonal dimensions. I am seeing a 3/16" difference in the diagonals. 49 6/16" for one diagonal and 49 9/16" for the other. I’ve used tie wire based on a forum post and I can bring the diagonals to within 1/16".
BUT, even if I retighten the screws to “lock in” the y-axis rail positions, and then cut the tie wire, the whole thing flexes back to my 3/16" difference.
I don’t feel like I can keep the tie wire on during the concrete pour because I need to add on the y-axis rail stiffeners and the baseplate and I think the tie wire would interfere.
Would it be ok to pour my 7 bags of concrete, add in the y-axis rail stiffeners and the base plate, add the last bag, and then try to use tie wire to bring in the diagonal dimensions while the concrete is still setting?
