My new capacitive ABL kits are now available at https://www.ebay.com/itm/233183828678
with a competitive price @ $39.99, pre-configured firmware for Ender 3/3 Pro, CR-10 Series, and other non-creality printers that use a 2-wire normally closed Z endstop !!! Setup is extremely easy ,,, mount the probe (OEM Bracket), plug in power and the Z end stop connector, upload the ready-to-flash firmware and calibate!

The kits have Vanilla Marlin firmware coming that has SD card & thermal run-away support.
