![]() ![]() I measured the height at approximately 13mm off the bed. Then deploys the bin on the BL touch, lowers to touch the bed until the pin registers, and repeats the process a second time and moves back up and stops even higher. Head moves to original X/Y, 0/0 axis and then proceeds to move to the center(ish) of the bed with the probe.The probe z_offset will then be calculated from these measurements. ![]() The Klipper PROBE_CALIBRATE tool can be used to obtain this value - it will run an automatic probe to measure the probe's Z trigger position and then start a manual probe to obtain the nozzle Z height. The parameters specified are X, Y and Z position.The z_offset is the distance between the nozzle and bed when the probe triggers. I printed my mount, which gave some suggestions on the mount offset. This will vary depending on your printer and what mount you're using. Using the Creality BLTouch Kit bracket, mine is Modify this line to specify where the probe is located. In Marlin 2.x, they're now combined in NOZZLE_TO_PROBE_OFFSET. Measure your XY Offset.Z_PROBE_OFFSET_FROM_EXTRUDER. To get a proper first layer height, the distance from the nozzle tip to the bed must be known at the point when the probe triggers. The bottom of the BLTouch plastic shell must be 8mm+-0.5mm away from the nozzle tip to trigger properly. #define X_PROBE_OFFSET_FROM_EXTRUDER -40 // X offset: -left +right #define Y_PROBE_OFFSET_FROM_EXTRUDER -12 // Y offset: -front +behind [the. The longer cable that comes with this is way more than adequate, so no complaints there. Select Control ยป Initialize EEPROM.The original wire I got with my BL Touch was short, so I had to end up soldering longer wires. Follow these steps to calibrate the offset: Auto home the 3D printer. Step 8 - Swap cases & boards.Calibrate the Z Offset for the BLTouch Probe The updated printer firmware will allow you to set the Z offset, which controls the position that the printer considers to be "0" directly on the print bed. Then click the button on the top left with an arrow pointing right. Ensure under Tools -> Board is set to Mega 2560, Tools -> Processor is Mega 2560, and you've selected the proper port. Connect the MKS Gen L board to the computer with Arduino IDE installed. Wires on bltouch on board are plugged in this order.Step 6 - Flash Firmware. I get a message of "Endstop z still triggered after retract" I've tried going through steps on this site (Connecting BL-Touch | klipper) but didnt work. It will move to start homing and then probe wont deploy at all. I am having trouble with the bltouch when homing. Wires on bltouch on board are plugged in this order.Getting Klipper setup on Ender 3 with 4.2.7 board and BLTouch 3.1. ![]() Now everything is ready to start adjusting the Z-offset value of your Kingroon KP3S.Getting Klipper setup on Ender 3 with 4.2.7 board and BLTouch 3.1. Run BL Touch on Kingroon KP3S: BLTOUCH 1. Set 3 (grid points) as bed leveling method. Then, place the previously printed square under the sensor and screw it in place.Normally, we don't need to change the value of X probe offset from exand Y probe offset from extruder. With the printer off, turn the Z motors clockwise and carefully lower the nozzle. Now that the firmware is flashed, and the sensor is installed we can set the probe offset. ![]()
