I’ve been working on other parts of the Behemoth while waiting for the Y axis parts to arrive. In order to cool the ramps and the steppers I decided to place an 80mm fan at the end of the aluminium tube. It will pull air out of the tube. At the other end of the tube I made a mount for the ramps and the LCD click controller. This cooling arrangement will pull cool air from the ramps side and exhaust the hot air out the fan side.
I think I’ll work on some support legs next.
