### Basic Information: Printer Model: Ender 5 Pro MCU / Printerboard: SKR 1.4 turbo Host / SBC Raspberry Pin3B klippy.log [klippy.log](https://klipper.discourse.group/uploads/short-url/l9C7w4z5mr1pFzZiUvNadXHhgwb.log) (156.1 KB) ### Describe your issue: I’m having trouble getting the Start G-code correct. As of now the extruder keeps smashing into the bed. I’ve performed the Z offset as per klipper instructions and saved this. So, I’m not sure what’s going on? Any advice on this would be most welcome ![IMG_0222](https://global.discourse-cdn.com/free1/uploads/klipper/original/2X/5/5c2efd41ca189530547b4d817396a79fe51bf186.jpeg) ---

Hi, it’s a genuine BL touch ---

So, why do you use `pin_up_reports_not_triggered` that is recommended for clones?

I suppose I didn’t know, but it has functioned correctly in the past. This is what’s happening When you start a print 1. Probes centre of bed 2. Heats bed to 60 3. Does a bed mesh 4. Extrude moves to rest pos. 5. Extruded heats 200 6. Draws 2 lines 7. Then right after drawing the lines it lift the z axis up into the extruder. (Where I have to switch off) This is what’s in the g code of the slicer (super slicer) ![IMG_0027](https://global.discourse-cdn.com/free1/uploads/klipper/original/2X/9/9a4659226a4e44f7336e1f0e6ffcdc15dc8e0e2e.jpeg) ---

1. ``` Probes centre of bed ``` `G28` (actually, it’s homing) 1. ``` Heats bed to 60 ``` `M190 S60` 1. ``` Does a bed mesh ``` `BED_MESH_CALIBRATE PROFILE=mesh1 METHOD=automatic` 1. ``` Extrude moves to rest pos. ``` `G1 X10 Y15 Z30 F4000.0` 1. ``` Extruded heats 200 ``` `M109 S200` 1. ``` Draws 2 lines ``` ```auto G1 Z2.0 F3000 G1 X10.1 Y20 Z0.28 F5000.0 G1 X10.1 Y150.0 Z0.28 F1500.0 E15 G1 X10.4 Y150.0 Z0.28 F5000.0 G1 X10.4 Y20 Z0.28 F1500.0 E30 ``` 1. ``` Then right after drawing the lines it lift the z axis up into the extruder. (Where I have to switch off) ``` And here ends the `START_PRINT` macro. So that macro is OK. Have you checked with a different model? You may can upload a (zipped) gcode file that makes trouble. There is maybe some wrong settings in the slicer. ---
