Hello everyone,
I have an ender 3 max neo with the bl touch. My original 4.2.2 board no longer functioned so i upgraded to the 4.2.7 board.
Now my sonic pad wint work correctly, the motors dont move.
Does anyone have a printer.cfg or a firmware that i can upgrade to so it will work again?
Thanks
you would figure Creality would add the max 3 Neo with BL touch and 4.2.7 firmware to the sonic pad update. Since these are all their products and should continue to offer support. But thanks to TNTSERVER on reddit who has a walk through and solution on how to fix this problem. Here is the link
https://www.reddit.com/r/SonicPadCreality/comments/1aupnaz/ender_3_max_neo_427_board_with_sonic_pad/
Select the “Ender-3 Max Neo”, when setting up an Ender-3 Max Neo printer, from the Sonic Pad printer setup screen. Flash the firmware it creates for you. All you need to do now is open the “printer.cfg” file and edit the STEP and DIR pins for each motor (X, Y, Z, and E). Sway the pin names between the STEP and DIR pins for each one. For instance, for [stepper_x], change the “step_pin” from PC2 to PB9, and change the “dir_pin” from PB9 to PC2. Save and restart firmware and you should be good to go. Here’s a copy of my “printer.cfg” file if you’d just like to copy and past it…
# !Ender-3 Max Neo
# printer_size: 300x300x340
# version: 3.6
# This file contains pin mappings for the stock 2020 Creality Ender 3
# MAX. To use this config, during “make menuconfig” select the
# STM32F103 with a “28KiB bootloader” and serial (on USART1 PA10/PA9)
# communication.
# Because this printer has factory wiring, mounts, and firmware for
# a BLTouch, but does not ship with one at this time, default values
# for the sensor have been specified, but disabled, in anticipation of
# future revisions or user modification. User should take care to
# customize the offsets, particularly z-offset, for their specific unit.
# Flash this firmware by copying “out/klipper.bin” to a SD card and
# turning on the printer with the card inserted. The firmware
# filename must end in “.bin” and must not match the last filename
# that was flashed.
# See docs/Config_Reference.md for a description of parameters.
