Hello, I bought a 1000x750 kit but im about to give up after spending the last 16 hours or so trying to make the 2 gantry plates arrive at the same time to the axis end. - when the first wheel of one plate touches the aluminium, the other one, is maybe 2mm away from it. I think i've tried everything by now, measuring, marking, screw the 5 Hole 90 Degree Joining Plate tight, loose, but one side is always offset. The 20x80 profiles are 74,5 cm away from each other in both ends. Can someone give me some tips or ideas? I can't spot where the issue is coming from. Do you think i can get away with this diference? I can take pictures or make a video if you think it can help. Thanks in advance. Best regards, Paulo.
