FLSUN QQ-S Bed Level Switch (Direct Sticky plate replacement!)

thingiverse

The FLSUN Delta Printer Series QQ-S came with a quirky sticky plate for auto leveling. Later versions arrived with a switch, which can also be purchased as an upgrade for $24. This kit is quite intricate to install and not particularly pleasant because it requires opening the bottom, resulting in wires dangling out. As makers, we've just completed our own Clip ON auto leveling switch. The cost? Absolutely nothing, and the experience was thoroughly enjoyable. There's no need to endure all that hassle of opening the base, reconfiguring any wiring, only to be left with loose cables protruding from under the printer like the FLSUN Switch solution. A standard microswitch, a spring lying around (which just fit snugly around the nozzle) were used to create good ground contact with the heat block. Fusion 360 was also employed in this endeavor. All that remained was adjusting the >Z_PROBE_HEIGHT to 4.5 in the Robin Mini config.txt file and re-flashing the printer. Watch the entire process unfold here: https://youtu.be/JjT5ktiIY2o
