Hello, I have an U30 and was running bltouch on a V08 mainboard for a long time with marlin. Due to another defect I needed to change the board and have now a V0H version. I connected the bltouch v3.1 as instructed with 10k ohm resistance and changed the used pin in marlin from PE5 to PD 13. #if HAS_Z_SERVO_PROBE #define SERVO0_PIN PD13 // Open drain PWM pin on the V0G (GND or floating 5V) #define SERVO0_PWM_OD // Comment this if using PE5 //#define SERVO0_PIN PE5 // Pulled up PWM pin on the V08 (3.3V or 0) //#undef Z_MAX_PIN // Uncomment if using ZMAX connector (PE5) #endif When starting BLTOUCH does it self test 2 times and stays in red. M280 P0 S10 is not working, also self-test via menu is not working neither deploying or stowing amanully. I also tried a 5.5 K and 10k ohm resistance. but both to not work. Any idea on the V0H board? Thanks in advance.

Thank you for the tip, double savings helps. I also managed to Z Probe offset moving by activating Babystepping in the config_adv.h. Now I can adjust Z Probe Offset directly without going back and forth. It's much more accurate adjusting with steps than X.XXmm.

Hello, sorry for not speaking french. I have an U30 with V08 board. I successfully managed to compile marlin 2.0.7.2 and runs it. But I have a few issues I can't solve by myself. Eventhough eeprom is activated there is no eeprom.dat written to SD card. However when I save setting with M500 I get no error message. My settings are not saved. 2nd I have installed a BLTouch and it is running OK. But when changing the Z Probe Offset it's not moving like I saw in some guides. I have to set it to some value and then calibrate by moving Z and calculation the right offset. I attached my config and config adv. Hopefully someone can help.
