Hi everyone,
I recently just installed a BLtouch on my Folgertech 2020. The problem I'm having is when i run the G29 (auto level) command the BLtouch drops the pin and the Z-Axis descends like it should, but when the touch is triggered the Z-axis keeps moving down. I won't stop until I either do an "emergeny stop" or I just unplug the power. I'm assuming its an error in the settings and/or firmware (Marlin 1.1.9) but I'm not sure how to fix it. Any help or advice would be greatly appreciated.

Thanks!
