Purchased this enclosure on the specs detailed for my millright mega v. First problem the inside measurements states it is 27" in length. My machine is 26 7/8". The actual inside measurement for the 510 is 26 3/4". Second problem is the measurements for the door panels are 645mm length x 556mm w. Had tap plastics cut the panels to those specs and they do not fit in the door frames at all, the width is 12mm off. Need help on this one. Followed the video and still not fitting.
Create a support ticket with the shop and they will help you work this through. And you're right, 680mm is not 27". There is no justification for sloppy conversions. We all count on reasonably accurate specifications.
