Sapphire plus
Simplify 3D
Revo hotted with orbiter extruder and no other major upgrades.
I have a Sapphire Plus with dual z end stops. I have being trying to install a bltouch clone (touch3d) on it and ran into an issue. The robin nano v1.2 that came in my printer only has 4 end stop pinouts (x, y, zmin and zmax). I need all 4 to run my x, y, and z on this printer because z is a bit sloppy when the machine is powered off requiring both endstops . I was wondering if it would be possible to use one of the filament runout ports (PA4 or PE6 on the robin) to connect the control pin from the bltouch to?
I am running Klipper and have tried both PA4 and PE6 but been unable to get it to work. All I get is a red light flashing on the bltouch and a massage “Failed to verify BLTouch probe is raised; retrying.”
Below is my Klipper config file.
# This file contains common pin mappings for MKS Robin Nano (v1.2.004)
# boards. To use this config, the firmware should be compiled for the
# STM32F103. When running "make menuconfig", enable "extra low-level
# configuration setup", select the 28KiB bootloader, disable "USB for
# communication", and select USART3 for the "Serial Port".
# Note that the "make flash" command does not work with MKS Robin
# boards. After running "make", run the following command:
# ./scripts/update_mks_robin.py out/klipper.bin out/Robin_nano.bin
# Copy the file out/Robin_nano.bin to an SD card and then restart the
# printer with that SD card.
# See docs/Config_Reference.md for a description of parameters.
