I’m in the process of installing a BLTouch on a Velleman Vertex K8400. The board doesn’t have a dedicated servo pin, so I’ll assign one. No problem there.
The board only has a Z-min pin, so it’s my understanding that I’m supposed to unplug my Z-min cable and plug the BLTouch into the Z-min port.
My question is: "Can't I assign another unused pin as a Z-max, plug the BLTouch into that, adjust the firmware, and leave the existing Z-min sensor plugged in?"
Upon further review, I probably shouldn't have said Z-max, and will be more specific.
This is a Mega 2560 board with 2 available PWM pins. Anything wrong with this setup?
#define SERVO_0_PIN 15 //PH3 (PWM) #define Z_MIN_PROBE_PIN 16 //PH4 (PWM)
=======Z Probe Option======= #define Z_MIN_PROBE_ENDSTOP #define BLTOUCH
I want be able to keep my Z-min sensor plugged in as a backup to prevent a bed crash just in case the BL touch doesn't trigger. From what I see this should work as long as I make sure the BLTouch triggers before the Z-min. Any issues that anyone can see?
