Does anyone have a working Klipper config for GTM32_103_V1 controller? The board has 7 TMC2208 drivers and is around $35 on ebay right now so I’m thinking of getting one.
Since it is a common STM chip and Marlin/pins_GTM32_103_V1.h at 2.1.x-geeetech-a30t · TheThomasD/Marlin · GitHub has a pin definition, the chances are good to setup a config for it.
Ok, I bought one. I started the config based on Marlin config, however I cannot seem to find PDN_UART settings.
Here’s what I got so far:
# This file contains common pin mappings for the GTM32_103_V1 board. Untested.
#
# INSTRUCTIONS FOR COMPILING
# 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, serial USART3 PB11/PB10 to use LCD serial
# to use direct UART connection with Raspberry or USART1 PA10/PA9 for USB communication.
#
# See docs/Config_Reference.md for a description of parameters.

EDIT: Well, Geeetech have decided to hardcode stepper current and microstepping. Fortunatelly soldering UART wires will not be difficult as PD_UART on TMC2208 is routed out and SD CARD pins can be used.

To update on progress, after removing pull-down resistors connected to pin 14 (PDN_UART), I soldered a jumper wire between pad from removed resistor on pin 14 of each TMC2208 and SD CARD connector’s signal pin (7 in total). Testing of UART failed at first…until I realized that I have to power the board via board power connector, not USB which only powers the MCU only.
In summary, wiring SD CARD pins to PDN_UART of each TMC2208 allows software driver control including current and microstepping. SD CARD is not needed since flashing via USB works just fine.
I’ve got that board running with klipper since almost a year now (in my geeetech A30 with a Sprite Pro hotend) …works great!
Although without sd-card and display; and I just use the PWM for the TMCs.
Didn’t think of wiring up the UART.
So, have you finished your config?
I don’t have A30, just need a cheap 7 driver board for my project. Can you share your config?
Here is my printer.cfg (with some old pieces removed)
Be aware: it was OK for me, but surely far from perfect! And atm it’s quite messed up as I went for a larger nozzle and I’m still in tuning things…but as e reference it should be OKish.

Hi, I have this board and I’m trying to install klipper on it, however I can’t get it working, all I get in the logs is this:

I am in the same boat here, I flashed the binary on my GTM32_Mini_S board and it does not work. I am wondering if it should be flashed to a different address. Did you ever get it to work ?
@ZweiStein , @w00sh Could you please share your menuconfig settings ? when I flash mine on GTM32 Mini S, klipper does not respond. Any instruction would be appreciated.
Thanks
No, I didn’t manage to get it work… however I haven’t had much time to troubleshoot the issue.

hey man i got the exact same setup as you. I have a BTT skr e3 v3.0. have you messed with your printer.cfg or it the same as posted
Hello @ty1994 !
Have you tried out some of the configs posted here?
honestly i haven’t found any my board sparked up today for my heater bed so now I’m running back through to see if I missed anything.
