    I am having a issue now. I followed the Marlin walk through to compile my own firmware for the E3D Hemera with a BLTouch(https://e3d-online.zendesk.com/hc/e...Hemera-Creality-Ender-3-V2-Firmware-Bl-touch-). Now the Z0 on the printer is 24 mm above the bed. When I try to set the z off set it will not go more then -10 to + 10. So I can't get my nozzle to print on the bed. Below is my read out from Pronterface. I have also attached my pre compiled files to see if someone can help. Please advise if any other information files are needed

    I'm having the same issue. I've releveled my bed multiple times, and have my z-offset dialed and saved to eprom through Pronterface, but when I start print my nozzle will start about 2 millimeters above print bed, and if I lower it the nozzle will crash into bed and drag. I've not been able to fix this issue.
