Finished my 750mm X-Carve a few days ago and thought I’d throw this out there for anyone yet to put theirs together: Get a set of dental picks! Not the big clunky mechanic’s pics, but something like these.
They’re great for centering the washers inside the v-wheels, but they really shine when it comes time to route your belts! With one of these and a flashlight I was able to route the X-axis belt completely through from the side, rather than coming in from the top in the middle like the instructions advised. MUCH easier. And if you’re worried about damaging your belts, you’ll have WAY more than enough to cut off the first few inches where the pick hooked into it when you’re done.
Roll the carriage over the belt and loop until the top of taped portion is directly under the pulley for the x-axis. This should leave the loop you made between one of the idle wheels and the pulley if you’re looking directly down on it through the carriage:
