Yes I did try a V6 but it was a pain in the bum and costly. And if you remember I gave the £500 printer away in the end. I haven't got to upgrade or fix to use a new hotend\extruder. I have added more to my printer to make life easy. Bluetooth cost me $10 and £1 for the wire E3D do kits for proprietary Printers. You don't see proprietary printer makers making kits for any other printer.
