Thermal Runaway on Ender 3 using ABS

  • I have been attempting to print with ABS on my Ender 3 but keep getting Thermal Runaway. I have upgraded my printer with BLTouch and an all metal hotend. I have printed since installing the BLTouch but have yet to print with the all-metal hotend. I have the v4.2.7 motherboard installed. I am a noob with 3d printers and am unsure where to start with this problem
