Bltouch not sending signal
April 19, 2019 12:02PM
My bltouch on my kossel doesn't work. It looks like it is working, but will never trigger. M43S does not detect a trigger (https://gyazo.com/46704223aa13e1f190995588cc585d81)
When i disconnect the bltouch, it says triggered, like it should be. And i read that ENDSTOP_INTERRUPTS_FEATURE sometimes fixes this, but i can't enable it because im using tmc2208 (Select hardware UART for TMC2208 to use both TMC2208 and ENDSTOP_INTERRUPTS_FEATURE)
Does someone know how to fix it?
BTW, it is on the y_min pin for testing, also works with z_min
Using marlin 2.0 bugfix with SKR v1.3 mainboard, 3 TMC2208 drivers in uart, and 1 A4988

Is it a BLTouch V3? If so, you’ll need some additional code added to Marlin to make it work.

GitHub link has the required changes to make the V3 work with Marlin.
