If you get the ” No Trigger on Probe” issue on Kingroon KLP1 3D printer, please adjust the leveling sensor, it should be about 1mm above the nozzle. To adjust it, please open the extruder, loose the screw that fixes the sensor, then adjust it. You should be all set then.
If your printer gets a noise when homing the axis, please check the adjustment of the bed.
Just check take a close look at the couplings, they should have some gap between the top when the Z-axis homed.
If not, the knobs under the bed should be too tight, loose them should fix the problem.
