### Basic Information: Printer Model: Ender 3 Pro MCU / Printerboard: BIGTREETECH SKR MINI E3 V3.0 Host / SBC Raspberry Pi 4B+ _Fill out above information and_ **_in all cases attach your_ `klippy.log` _file_** (use zip to compress it, if too big). _Pasting your_ `printer.cfg` _is **not** needed_ _ **Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there** _ ### Describe your issue: I switched From Klipper 2 months ago and i have problems while printing. I use cr touch and the bed mesh to get as much accuracy as i can, but it almost never prints something correctly. Most of the times it fails. In some areas the z offset is too much and in others too small so i never get the results i want. I always do the probe calibration and in my slicer settings I run the BED\_MESH\_CALIBRATE command but it always fails.Also, I have experimented with many values of heater bed but from the previous firmware i believe that around 60 Celsius is great for PLA. Here is my printer.cfg ```auto [include mainsail.cfg] # This file contains common pin mappings for the BIGTREETECH SKR mini # E3 v3.0. To use this config, the firmware should be compiled for the # STM32G0B1 with a "8KiB bootloader" and USB communication. # The "make flash" command does not work on the SKR mini E3. Instead, # after running "make", copy the generated "out/klipper.bin" file to a # file named "firmware.bin" on an SD card and then restart the SKR # mini E3 with that SD card. # See docs/Config_Reference.md for a description of parameters.

As for the bed mes in the klippy.log ```auto [bed_mesh default] version = 1 points = -0.157500, -0.057500, -0.047500, 0.000000, 0.055000, 0.080000, 0.150000 -0.177500, -0.100000, -0.030000, 0.015000, 0.032500, 0.090000, 0.177500 -0.187500, -0.087500, -0.057500, -0.005000, 0.095000, 0.130000, 0.212500 -0.207500, -0.132500, -0.087500, -0.030000, 0.067500, 0.137500, 0.215000 -0.180000, -0.055000, -0.045000, 0.002500, 0.082500, 0.130000, 0.227500 -0.192500, -0.117500, -0.025000, 0.027500, 0.077500, 0.117500, 0.265000 -0.140000, -0.037500, 0.002500, 0.072500, 0.135000, 0.195000, 0.287500 x_count = 7 y_count = 7 mesh_x_pps = 2 mesh_y_pps = 2 algo = bicubic tension = 0.2 min_x = 40.0 max_x = 190.0 min_y = 40.0 max_y = 190.0 ``` The is almost up to a half a millimeter difference in the bed. For you have `[screws_tilt_adjust]` setup in the config, did you already levelled the bed by `SCREWS_TILT_CALCULATE` See: [https://www.klipper3d.org/Manual\_Level#adjusting-bed-leveling-screws-using-the-bed-probe](https://www.klipper3d.org/Manual_Level#adjusting-bed-leveling-screws-using-the-bed-probe) ---

Yes i have leveled the bed with the SCREWS\_TILT\_CALCULATE method. ---

Have you tried to do the `BED_MESH _CALIBRATE` after completing heating the bed? ---

Yes, I tried it now, it stil doesnt print correctly. Unfortunately itdoesnt stick on some points, so it oozes and ruins the whole print ---

Still wondering why there is such a huge deviation between left and right of the bed ---

Also try [Axis Twist Compensation](https://www.klipper3d.org/Axis_Twist_Compensation.html#axis-twist-compensation) The Enders are notorious for twisted axes. ---

I rerun the SCREWS\_TILT\_CALCULATE and these are the new logs. I tried printing but again nothing. [logs-20240603-205907.zip](https://klipper.discourse.group/uploads/short-url/wf9PM39jFvCChG2tazDEkaofiKl.zip) (260.8 KB) ---

> [@Brear](#): > > Ender 3 Pro One of my enders was showing similar symptoms and it turned out to be a combination of two mechanical issues for me. The gantry had worked loose due to wear on the wheels and I found I could move it up and down about 2mm on the opposite end to the driven side where the leadscrew is. After I adjusted the slack out of the gantry I was still having issues and it turned out to be coming from binding on the leadscrew.nut. I probably could have fixed that with and oldham coupler on the leadscrew nut or something similar but I ended up doing a belt ender conversion (from Kevinakasam) and it’s been almost hassle free ever since. My bet is warped like a pretzel too but the bet mesh accommodates for that fine now. ---

Some settings that helped: stow\_on\_each\_sample: False probe\_with\_touch\_mode: True pin\_up\_touch\_mode\_reports\_triggered: False set\_output\_mode: 5V also a “probe\_accuracy” to make sure the probe is working correctly. ---
