Frame Slightly off Square on Ratrig VCore 3.1 400 Enclosed
Just finished the gantry and EVA and noticed that there is about 1mm of space ahead of the left Y bumper, while the right it flush. I tried to loosen the screws on both Y carriages and the pully screws for each side of the gantry, but this didn't fix the issue. I did try loosening the left rail and retightening after moving Y forward and back, and same result.
To keep checking, I measured the spacing in left and right, which seem fine. Diagonally, however, the spacings were 900mm and 902mm. Everything Else I've measured seems fine or is different by less than 0.5mm. One thing to note is that I have not tensioned the belts with any tuning, but they seem to be relatively tight and similar to each other. Additionally, I did not notice any change in the misalignment during tightening.
My main concern is that I notice an occasional (but consistent) judder when the left motor is spinning when I move the toolhead by hand. I have not tried moving the toolhead by the motors yet as my electronics are not set up yet and I still need to get some of the final wires. I'm not sure if the juddering is solely because I am moving it by hand, or if it is from something else. I also wasn't sure if the ~2mm difference would be an issue or not considering everything else seems to be ok. For all I know, it could just be the position of the corner plates being slightly off.
Any assistance or advice would be much appreciated!
Thanks,
Dan
