Printrbot 1405 Front end and YZ plate

thingiverse

Here's how you can make a modified version of iamjonlawrence's frontend and YZ plate to prevent overheating. The original frontend is replaced with one that uses the stock 1405 wooden mounting plate, which keeps the extruder's heat away from the plastic components and stops melting/warping. The modification includes a slightly changed YZ plate where you mount the Y endstop about 10mm further back. This increases its travel range. Instructions Replace the original frontend with one that uses the stock wooden extruder mounting plate from the 1405. You need to cut down the square tab on the rod side of the wooden mount, and then install it in the printed frontend.
