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

cults3d

The FLSUN Delta Printer Series QQ-S arrived with a quirky sticky plate for auto leveling. Later versions featured a switch that could also be purchased as a $24 upgrade. This kit, however, was notoriously difficult to install and presented several drawbacks - it required opening the bottom, resulting in wires protruding from the printer. As makers, we take pride in our ability to create and innovate. I recently completed my own Clip ON auto leveling switch project, which not only cost nothing but was also a fun challenge to tackle. Unlike the FLSUN Switch solution, my DIY approach eliminated the need for invasive base modifications, rewiring, and the resulting mess of loose wires beneath the printer. To design this custom switch, I used a standard micro switch, a spring that fit snugly around the nozzle to ensure good ground contact with the heat block, and Fusion 360 software. The only adjustment required was updating the Z_PROBE_HEIGHT setting to 4.5 in the Robin Mini config.txt file before re-flashing the printer.
