### Basic Information: Printer Model: Flsun V400 customized with E3D Revo Micro + Bondtech LGX Klippy log: [klippy (6).log](https://klipper.discourse.group/uploads/short-url/wLfV3YHNpfJJIWe02DGlI6eZchN.log) (348.4 KB) Hi there, First time post, so hi and nice to meet you! I am fairly new to Klipper as I always had Marlin printers. Since half a year I print with a Flsun V400 delta printer. Nice, but also more problematic. So I installed the official Klipper a few months ago and recently I changed the whole setup after a massive filament explosion due to a crappy hotend (screw missing and cheap setup). So now I have a Revo Micro HF installed and it sits quite a bit higher than original. So the probe distance to the nozzle is also larger. Don’t know if that is the problem, but whatever I do, the nozzle keeps hitting the bed. I do a automatic Z offset calibration via the menu and it gets saved in the end. And I even apply a safety offset of 2mm and set the nozzle quite a bit from the bed to be sure. None helps… I’m quite desperite now and my new Revo gets al messed up with all those bed hits. EDIT: Maybe also good to know: I lowered the bracket for the probe with a few mm too, as it was the same height as the nozzle. Hope someone can help me, I’m even willing to pay… Thanks! Below is a photo just after probing (not set the z offset yet). Can someone explain the data shown? ![Probe offset](https://global.discourse-cdn.com/free1/uploads/klipper/original/2X/1/14e8f0237b3ec13f7b957dbc36ffb2cc5a0c5f4a.jpeg) ---
