Z height

Hi I change my hot end over to a e3dv6 heartbreak and heatsink but with the original heater block and I believe my Z height at 450 is no longer adequate. How do I go about finding the correct Z height. Thanks

Someone else may have more insight and a better answer, but here's what comes to mind. From a USB connection and terminal (or host):

• first, home with G28
• and set the height with G29 P0
• then probe the center (0,0) with G30 V3

During the tapping process, the G30 command should spit out information about the Z positions and offsets along the way. I think with this information, it should be possible to determine a reasonable offset to use with the M851 command. Then:

• set the probe (nozzle) z-offset with M851 Z<your offset here>
