Basic Information:

Printer Model: Ender 3 S1 Pro
MCU / Printerboard:

klippy (8).l

Host / SBC MAINSAIL

printer.cfg (11.5 KB)

klippy.log

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:

X and Y both home when z starts to home it says endstop_z still triggered after retract. if it doesnt say that the extruder just rams into the bed. im not very good with printers or coding really. thanks for the help. much appreciated!!!

Hi @Ulfhednar33 ,

Make sure you follow the initial tests described in the Klipper docs:

I am running a Pi Zero 2w with the original 401 main board on my Ender 3 S1 Pro, here is CR Touch setting:

[bltouch]
sensor_pin: ^PC14
control_pin: PC13
x_offset: -45.0
y_offset: 0
#z_offset: -1.12
probe_with_touch_mode: true
stow_on_each_sample: false
samples: 3
sample_retract_dist: 6.0
samples_result: average
samples_tolerance: 0.140

[safe_z_home]
home_xy_position: 147.5, 117.5
speed: 75
z_hop: 10
z_hop_speed: 5

Make sure to uncomment and add your z_offset before saving.

The “official” sample config for your printer can be found at

It seems you are able to connect so firmware should be good. If you downloaded a .bin from somewhere I recommend you recompile. Make sure to set the correct MCU when you “make” your firmware.
