This is an assortment of hardware I printed, including the standalone belt clamp with magnets, and the two mount plates with magnetic blocks. The magnetic blocks have four magnets on one side to grip the belt clamp firmly, and two on the other side to grip the parking position end stop a bit less firmly. Later I had to re-print the left extruder drive and left magnetic block in reverse (flipped across the X axis), so this hardware design is not final.
This is the left side end stop block with holes for two magnets (not yet installed). It is bolted to the frame using the machine screws that hold the X endstop switch. The belt passes through the slots without touching.
This is the right side end stop block with holes for two magnets (not yet installed). It is bolted to the frame with one of the X axis motor screws, and the screw holding the X axis nylon stop post. Again, the belt passes through the slots without touching.
In mid-project, with the second linear rail block on the rail, and both mount plates bolted down along with the motor mounts. This was when I realized that the left side extruder, mount plate, and motor mount would all have to be reversed so that the left extruder could be off of the bed when in the parked position.
More to come in the next post!
