Using the Slice Engineering Copperhead Hot Block is easy. First, replace your existing factory hotend with the Copperhead. Make sure it's properly installed and connected to your 3D printer. When printing, you'll notice a big difference in performance and fewer jams. For maintenance, regularly check the hot block for any signs of wear or debris. Clean it gently if needed. Keep in mind that while it's designed to handle heat well, don't overheat it beyond the recommended temperature. This will help ensure long - lasting and smooth operation of your 3D printer.
