Practically everything, but the frame has been upgraded and customized. Full metal print head , custom print head cooling, 32 bit controller with TMC2209 stepper...显示更多 drivers, touch bed level sensor. Added a second Z motor with of my own designed framed platform to stabilize the bed.
I basically have tweaked & upgraded this printer to work with whatever works best for the job and in depth understand the design of my setup to give you a nice consistent print every time. If you actually have read all this I thank you for considering us.
