Tina2S Klipper config

printer.cfg

# This file contains pin mappings and other defaults for the Weefun/Weedo
# Tina2s based on the GD32F103. It won't work with the ATMega-bsed
# Tina/Tina wifi/monoprice cadet.

# The biggest issue with this printer is that the USB-serial CH340G's DTR pin
# is tied to reset with a 1k resistor - not a capacitor circuit like most.
# restart_method of 'tina2s' was added to make sure DTR is held high during
# normal operation

# Pins were found in https://github.com/weedo3d/TINA2Sfirmware and confirmed
# on hardware. Flashing will not work with stm32flash or via makefile because
# of the DTR implementaiton. It can be flashed using the proprietary upload
# tool found in their repository. Factory firmware can be reverted with the
# same tool

# menuconfig options:
# [*] Enable extra low-level configuration options
#     Micro-controller Architecture (STMicroelectronics STM32)  --->
#     Processor model (STM32F103)  --->
# [ ] Only 10KiB of RAM (for rare stm32f103x6 variant) (NEW)

Needed to use this fork https://github.com/securelyfitz/klipper because of this Klipper3d/klipper#6126
Also used these macros https://github.com/jschuh/klipper-macros

The [gcode_macro M106] is basically a provisional dummy variable for the macros as the fanspeed can't be adjusted (at least not really).
