Mix G1 Extruder - JHead

thingiverse

I upgraded my MIX G1 printer with a jhead and made some modifications to accommodate the new hotend. I installed a jhead as an upgrade to my MIX G1 printer but encountered difficulties. Fortunately, I had previously applied modifications on my machine, which now prints beautifully! To enable installation of the JHEAD, follow this modification for your MIX G1 extruder: enlarge the opening for the hotend, add holes for two screws, and make body bigger. In order to fit my hobbed bolt inside, I made the body even bigger. Then I narrowed down the depth to allow these screws to work. Lastly, I added a mounting hole for an exhaust fan (a future project). Instructions: Make sure you have a modified X Cartridge with an increased opening to J-HEAD. If you're working with a pre-existing MIX G1 printer, those screws that originally connected the parts will still function (I reused them too). Just line up the holes on your X cartridge and the extruder part shown here; secure them together. This is sufficient for installing JHEAD, as two front middle screws are required to keep the head securely in place within the machine. In doing so, ensure a snug fit for JHEAD.
